With increasing life expectancy， neurodegenerative diseases have become one of the leading causes of ill-health in the elderly. Preventive strategies include following healthy diets， such as the Mediterranean diet， which is particularly rich in polyphenols， bioactive compounds with neuroprotective properties. The aim of this study was to assess the association of microbial phenolic metabolites (MPM) with cognition. This cross-sectional analysis was performed with 200 participants of the PREDIMED trial (Barcelona-Clinic recruitment center). A novel method based on liquid chromatography coupled to mass spectrometry was used to identify urinary MPM (protocatechuic acid， enterodiol glucuronide， enterolactone glucuronide， urolithin B glucuronide， and vanillic acid glucuronide)， and cognitive function was evaluated with neuropsychological tests. Multivariable-adjusted ordinary least squares regression was used to assess the associations between cognitive function and MPM， and a score was calculated as the weighted sum of MPM. A higher MPM score was associated with better frontal lobe function. Among individual metabolites， vanillic acid glucuronide was correlated with frontal cognitive performance. Participants with higher concentrations of vanillic acid glucuronide and urolithin B glucuronide obtained better scores in the Color Trail Test part 2. A higher score for urinary multi-MPM was associated with better frontal cognitive performance in an older Mediterranean population.

Chitin powder and chitin-aerogel were prepared from shrimp wastes and used to uptake Y^(3+)from aqueous solutions and concentrate this rare earth element from phosphogypsum(PG).Chitin aerogel displays a specific surface area of 945 m^(2)/g,while chitin powder is 3.6 m^(2)/g,which largely influences its adsorption *** the adsorption in synthetic solutions,the effect of pH on Y^(3+)removal is strong for chitin powder *** contrast,no big pH influence was detected for chitin *** interactions and chelation can highlight the proposed mechanism of Y^(3+)on chitin adsorbents for the powder and ***,in addition to these interactions,pore filling/pore diffusion is the main mechanism of Y^(3+)removal in the chitin *** aerogel is efficient in concentrating 8 times the Y^(3+)from PG,a very complex *** complex chitin aerogel-Y^(3+)can be a secondary source of rare earth elements for other applications.

In this editorial,we proceed to comment on the article by Chua et al,addressing the management of metastatic lateral pelvic lymph nodes(mllN)in stage II/III rectal cancer patients below the peritoneal *** treatment of this nodal area sparks significant controversy due to the strategic differences followed by Eastern and Western physicians,albeit with a higher degree of convergence in recent *** dissection of lateral pelvic lymph nodes without neoadjuvant therapy is a standard practice in Eastern *** contrast,in the West,preference leans towards opting for neoadjuvant therapy with chemoradiotherapy or radiotherapy,that would cover the treatment of this area without the need to add the dissection of these nodes to the total mesorectal *** the presence of high-risk nodal characteristics for mllN related to radiological imaging and lack of response to neoadjuvant therapy,the risk of lateral local recurrence increases,suggesting the appropriate selection of strategies to reduce the risk of recurrence in each patient *** the heterogeneous and retrospective nature of studies addressing this area,an international consensus is necessary to approach this clinical scenario uniformly.

本文旨在引入美国的人口统计分析模型,建立适合于在我国应用的人口统计分析模型.采取文献解读法和概率模型法,研究人口统计分析模型及其相关问题.研究结果表明:人口统计分析模型在我国的研究尚处于起步阶段,建立我国的人口统计分析模型,不能照搬美国的人口统计分析模型,而应该结合我国实际情况有所改进与创新;建立人口统计分析模型分为两个层次,一是建立基于全面资料的人口统计分析模型,无需计算抽样方差,二是建立基于抽样调查资料的人口统计分析模型,需采用刀切法近似计算其抽样方差;人口统计分析模型的优势是,充分利用了出生、死亡及国际迁移等人口行政记录资料,节约了数据采集成本,与人口普查独立,劣势是,估计结果具有不确定性,尤其是其中的国际净迁移人数的估计结果差异较大.人口统计分析模型有望应用于我国2030年人口普查净误差估计,开创我国在该领域使用人口统计分析模型的先河.
